"Why do advocates of the dangerous warming hypothesis resort to ad hominem attacks? Is it to protect science? If so, it is misguided. Progress in science depends heavily on research by skeptics. Or might the attacks be motivated by fear that people read skeptics' research and find it persuasive?...Science is a process. The results of that process do not depend on whether scientists are good or bad, altruistic or selfish. The issue is whether they follow the scientific process....Replication is more difficult than the 'follow the money' narrative behind the attacks on Mr Soon and other skeptical scientists. But for those seeking truth, it is the only analysis worth conducting." Dr Scott Armstrong, writing in the Washington TImes
